Although press brakes are relatively simple machinery, different configurations are generally flexible, allowing for the equipment of different accessories. This ensures different press brakes feature different tonnages, lengths, and strokes, making it necessary to choose the right one according to your production needs.

The following are a few key points to take into consideration when choosing a press brake:

One of the most important factors is tonnage, which indicates the press brake capacity.

• Traditionally speaking, the thicker or longer the material to be bent is, the higher the tonnage needed.
• Compared to stainless steel, carbon steel, or other high strength materials, softer metals such as aluminum and copper require less tonnage.
• The mold length and die opening width are also important factors. Traditionally, smaller vees mean a higher tonnage.
• Compared to bottom bending and coining, air bending requires a lower tonnage.

It should be noted that when choosing a press brake, the maximum tonnage should be 20 to 30% higher than what you actually need. This is to ensure the machine is capable of operating at a full load when working under maximum pressure, which affects the machine service life.

The press brake length depends on the maximum workpiece length that needs to be processed.
